However, the retainer members 91 are provided with an outwardly directed portion which is flanged radially outwardly as indicated at 98, and which is adapted to form a retaining flange for holding the bearing seal means 99 in position within the recesses 95. The bearing seal means 99 may be of any conventional type such as that employing two oppositely disposed cup members pressed together and retaining therein a leather sealing member or'the like. It will thus be apparent that the members 91 which are locked in the grooves 93 by prick punches or, if desired, by an annular rib portion, also serve as a means for retaining the bearing seals 99 in position. This allows the seals to be placed in position without the driving fit usually required against the shoula, result, does not tend to produce the outwardly flaring. of the ends of the race member 92, which has customarily beenproducediheretoforeby driving of the bearing seals into position. 1 j
